The spin crossover system, [Fe(bzimpy)2](ClO4)2·0.25H2O, was reinvestigated above room temperature (bzimpy = 2,6-bis(benzimidazol-2-yl)pyridine). system exhibits an abrupt low-spin to high-spin transition at Tc 403 K. Liberation of a fractional amount water does not affect the crossover: is perfectly reversible with hysteresis width ΔT 12 existence such high determines that lowest limit solid-state cooperativity parameter J/k > K despite long iron(II) separations (10 Å). cooperativeness has...
The corrosion resistance of Incoloy 800H/HT in FliNaK<sub>(eut)</sub> decreases upon addition fluorides the following order: CrF<sub>3</sub> > FeF<sub>2</sub> FeF<sub>3</sub> NiF<sub>2</sub>.
The condensation of 2-pyridinecarboxaldehyde N-oxide and triethylenetetramine yields a product with two imidazolidine rings, as proven by solid-state X-ray structure analysis well NMR solution spectra. This ligand, L1, undergoes ring-opening reaction on complex formation Cu(II), yielding [CuL2]2+ where L2 functions pentadentate containing only one ring. On complexation Zn(II) Fe(III), both rings are opened the complexes [ZnL3]2+ [FeL3]3+ hexadentate L3 ligand formed. recrystallization from...
The density and the viscosity of melts system (LiF + NaF KF)eut (1) K2TaF7 (2) Ta2O5 (3) have been investigated up to x3 = 0.02 x2 0.15. has measured using an Archimedean method. On basis densities, molar volumes partial volume in binary calculated. computerized torsion pendulum data was fit modified Redlich−Kister's equation.
The structures of several fluoroscandate compounds are presented here using a characterization approach combining powder X-ray diffraction and solid-state NMR. structure K5Sc3F14 was fully determined from Rietveld refinement performed on data. Moreover, the local NaScF4, Li3ScF6, KSc2F7, Na3ScF6 were studied in detail 19F 45Sc NMR experiments. chemical shift ranges for six- seven-coordinated scandium environments defined. bridging terminal fluorine atoms also determined. First-principles...
High-temperature corrosion tests of alloys, Nimonic 80A, Inconel 718 and C-276, were investigated at 680°C in molten alkali fluoride salt (LiF–NaF–KF: 46.5–11.5–42%) environment. In this work, techniques included weight loss measurements potentiodynamic polarisation curves measurements. C-276 showed better resistance, while 80A exhibited comparatively lower resistance. The high-temperature behaviour was observed using the oxide morphology thickness. rates determined by recording changes...
A series of compounds KTaF6, K2TaF7 and K3TaF8 KNbF6, K2NbF7 K3NbF8 was investigated by means XPS MAS NMR spectroscopy DSC measurements. Electron binding energies all accessible orbitals were discussed and, for the first time, correlations between different orbital examined. (19)F data other parameters correlated with structural information, as well data. Also a complete set presented including number phase transitions their heat contents. Based on measured characteristics it shown how...
